Forged in the wake of Mozilla’s decision to drop support for the entire Mac PowerPC platform, TenFourFox is a web browser which brings the Firefox experience to PowerPC Mac users, whether one is running a G3, G4 or G5 PPC. While there have been several attempts at furnishing PowerPC users with a compelling web browser, TenFourFox is perhaps the first to provide a Firefox build which is tuned so well to cater to the PPC platform, that it can offer remarkable JavaScript performance, offering a reported twofold benefit over Firefox 3.6 and surpassing even Safari 5 (which is only available for Leopard users) in some respects.

Clearly, the TenFourFox team are to be lauded for their efforts, but can they really deliver a modern, stable and secure browser to the aging PowerPC? Let’s take a look.
